Skushino,

Thanks for your kind words!

You ask a tough question! Nyquist rate converters & over-sampled converters are 2 quite diff. beasts with very little in common except for they perform the same function - D-->A. Diff. design tecniques are used, diff. pitfalls are looked into during the design.

Both designs can be made equally phase accurate & both designs can be equally botched!

In over-sampled converters some of the things one needs to consider are stability, quantization error, effect of in-band tones, non-linearity, which is are a diff set of criteria from Nyquist rate converters.

Which one is used depends on the application on hand & the cost factor.

Hope that this helps.
